Using mpl 0.99.1 and sometimes get the following exception.

I thought/guessed it had to do with not having resized the canvas
correctly, but I am not sure and the following code is run whenever I
resize the parent of the canvas.
def _SetSize( self ):
pixels = tuple( self.parent.GetClientSize() )
self.SetSize( pixels )
self.canvas.SetSize( pixels )
self.figure.set_size_inches( float( pixels[0]
)/self.figure.get_dpi(),
float( pixels[1]
)/self.figure.get_dpi() )
What could the cause of this error be?
